variable caot be accessed by the test

public class Saiyan extends PlayableFighter {
private boolean transformed;
public Saiyan(....)
{
    :
    :
}

public void isTransformed(boolean x){
transformed=x;

}
public boolean isTransformed(){
    retu transformed;
}

}

i think my transformed attribute should be read and write but when i run my test i get this error

M1PrivateTest.testSaiyanClassWRITEVariables 0/1  
   junit.framework.AssertionFailedError
   junit.framework.AssertionFailedError:
   The "transformed" instance variable in
    class Saiyan is a WRITE variable.

Change to

public void setTransformed(boolean transformed){
    this.transformed=transformed;
}
